Hello
I have a weird problem, in TOMAWAC the test case bottom_friction.
By varying the number of processors from 40 to 45 even numbers execute normally but odd one doesn't not execute, and for number greater than 45 it doesn't execute giving me the following message:
"
+>  /home/nheili/telemac_version/dot/builds/mpidot/bin/partel < PARTEL.PAR >> partel_WACGEO.log
At line 1006 of file /home/nheili/telemac_version/dot/sources/utils/partel/partel.F
Fortran runtime error: Index '19' of dimension 1 of array 'nbre_ef_loc' above upper bound of 18

Backtrace for this error:
  + in the main program
    from file partel.F
  + /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xed) [0x7eff2f9e176d]
... The following command failed for the reason above
/home/nheili/telemac_version/dot/builds/mpidot/bin/partel < PARTEL.PAR >> partel_WACGEO.log
"
Any ideas, knowing that the same code execute telemac2d well.

Best Regards

Hello Rafife,

We probably never tested with so many processors and it seems an error in the partitioner, though it could be the fact that there are too few elements in the original mesh.

With best regards,
